How Often to Refuel a New Car

New car owners often wonder how frequently they should refuel their vehicles to optimize performance and fuel efficiency. Generally, it is recommended to refuel when the fuel gauge reaches the quarter tank mark. This practice ensures that the fuel pump remains submerged in fuel, which helps to keep it cool and functioning properly. Additionally, it minimizes the risk of running out of fuel, which can lead to engine damage and inconvenience.

The reason behind this guideline is rooted in the design of modern fuel pumps. Fuel pumps are typically located at the bottom of the fuel tank and are submerged in fuel. When the fuel level is low, the pump is more exposed to air, which can cause it to overheat and potentially fail. Moreover, running on empty can cause the fuel pump to draw in air, leading to cavitation and further damage.

According to a study by the U.S. Department of Energy, the average fuel efficiency of a car decreases by about 2% for every 10% of fuel that is left in the tank. This means that maintaining a fuel level above the quarter tank mark can significantly improve fuel efficiency. Furthermore, the American Petroleum Institute (API) suggests that refueling when the tank is at least a quarter full can help prevent rust and corrosion in the fuel tank.

It is important to note that while the quarter tank rule is a general guideline, individual driving habits and vehicle types may necessitate more frequent refueling. For example, if you frequently drive in stop-and-go traffic or carry heavy loads, you may need to refuel more often. Conversely, if you primarily drive on highways at consistent speeds, you may be able to go longer between fill-ups.

In conclusion, refueling when the fuel gauge reaches the quarter tank mark is a good rule of thumb for new car owners. This practice helps to maintain fuel efficiency, protect the fuel pump, and prevent potential damage to the vehicle. However, it is essential to consider individual driving habits and vehicle specifications when determining the optimal refueling frequency.
